Technical Field

The invention relates to the field of rubber manufacturing, in particular to an engineering solid tire capable of resisting 50pphm ozone.

Background

At present, rubber is used as a tire tread when a solid tire for engineering is manufactured, common rubber is used when the solid tire for engineering is manufactured, the performance of a rubber tire manufactured by common raw materials is common, the abrasion of the rubber of the tire is easily caused under severe environment, the service life of the solid tire is influenced, the cost for replacing one tire is expensive, and the product sale is not facilitated. Therefore, it is very important to solve the problem that the service life of the solid tire made of the common rubber is shortened under the severe environment.

Disclosure of Invention

Aiming at the problems in the prior art, the invention aims to provide a 50pphm ozone resistant engineering solid tire, which meets the use requirement of the tire under the severe working conditions by optimizing a rubber protection system and adding long-acting protection wax into a formula, so that the tire still has a longer service life under the severe environment, and the problem of shortened service life of the solid tire manufactured by common rubber under the severe environment is solved.

The invention provides a 50pphm ozone-resistant engineering solid tire which comprises, by mass, 60 ~ parts of natural rubber, 20 ~ parts of styrene-butadiene rubber, 50 ~ parts of wear-resistant carbon black, 3 ~ parts of aromatic oil, 2 ~ parts of environment-friendly zinc oxide, 1 ~ parts of stearate, 1 5636 parts of an antioxidant, 2 ~ parts of protective wax, 2 ~ parts of sulfur and 3 ~ parts of an accelerator, wherein the solid tire comprises, by mass, 60 parts of natural rubber, 60 parts of styrene-butadiene rubber, wear-resistant carbon black, 3 parts of aromatic oil, 20 parts of environment-friendly zinc oxide, 2 parts of stearate, 2 parts of protective wax and 3 parts of accelerator.

The further improvement is that isocyanate and polyether are added into the solid tire, wherein the adding mass portion of the isocyanate is 5 ~ 15 parts, and the adding mass portion of the polyether is 8 ~ 20 parts.

The further improvement is that a chain extender and a surfactant are added into the solid tire, wherein the weight part of the chain extender is 8 ~ 9 parts, and the weight part of the surfactant is 2 ~ 4 parts.

The further improvement lies in that: after the solid tire is prepared, a layer of high polymer material needs to be sprayed on the surface of the tire.

The invention has the beneficial effects that: through the optimization of a rubber protection system, the long-acting protective wax is added into the formula, the use requirement of the tire under severe working conditions is met, the tire is enabled to still ensure longer service life under severe environment, the isocyanate and the polyether are added into the tire, the performance of the tire is improved, the use effect of the tire is improved, and after the preparation is completed, a layer of high polymer material is sprayed on the surface of the tire, so that the tire is isolated and protected, and the service life is prolonged.
